Marin County: Bon Tempe Lake - Lake Lagunitas Loop

San Francisco: Marin Headlands - Mt Tamalpais - Point Reyes

The Marin County Watershed encompasses 5 lakes which dot the base of towering Mount Tamalpais. Among them are Bon Tempe Lake and Lake Lagunitas, which join to form a beautiful 6.25 mile figure-eight loop. The loop hike is easy and peaceful - particularly in the morning when crowds are thin. The 5 watershed 'reservoirs' provide the drinking water for surrounding Marin County and also offer a wide range of family-friendly recreational activites from hiking to biking to fishing.
